Re: Dynamic numeric range

[Greg Miller <gs...@gmail.com>]

I think this is super interesting to explore! It would be useful to
have an implementation like LongRangeFacetCounts /
DoubleRangeFacetCounts that "discovers" its own ranges based on the
distribution of the underlying data, rather than requiring the user to
specify the ranges up-front.

Could you please create a Jira issue to track this work? That would be
a good place to track progress, as well as any suggestions others
might have on how to best implement this. Thanks for bringing up the
idea!

Cheers,
-Greg
